Topic: New build from France (Read 2484 times)

hello everyone, first of all my apologies for my bad english.I am a french who started in the world of drones and when I saw your construction I decided to start too!I printed all the pieces in pla on a small french printer. the arms in 70% and the rest in 30%.the motors are brushless 2212 980kv.esc 20a opto bhleli.the FC is the naza m lite with gps neo m8n.the transmitter is a ia6c with a radio turnigy evolution.I just finished all the config radio and FC and I look forward to my 8045 propellers for the first flights.I still have a doubt for the arms of the drone, even with the springs plungers I'm afraid that the arms fall back during the flight (and I tightened the m3 like a sick)when I understood how to put pictures I would show you the beast!

Thank you very much Mkc2! I am really a beginner in the world of drones and modelism in general ... what do you mean by removing the negative cable of esc? are you talking about the esc / motor connection?

If the first flight goes well, I would like to try to install a 3-axis gimbal with a small camera like the runcam split 2, I have an old gopro hd2 too but I think it will be too heavy.

I hesitate between manufacturing the gimbal or buy a not too expensive like a tarot 3d ... is it complicated to do?

I prefer to build it because it's more exciting but I do not know if I have the level to do it and if it is not more expensive in the end ... to see!

hello patrick (and everyone)!I will not speak French on this topic if the others would not understand us! where are you from the construction of your drone? I wait impatiently propeller for the first flight ... or crash, we'll see ...in the meantime I ask myself a lot of questions about the configuration of naza lite.besides, I have a question about the blinking LEDs. I plug the lipo, I have the ignition sequence (I'm in manual mode) then it blinks 3 times then 2 times and 1 time and after nothing. when i switch to atti mode i have a regular blink in orange and in gps mode 1 regular blink green.everything seems ok but I read everywhere on the internet that there should be a quick flashing of green led for the recording of the home point and the end of the initialization ... but I do not have it .in the manual of the lite I have not seen a mention on this famous green flash so I think it's good but I prefer to seek the advice of experts!thank you in advance !

The wire from your esc that go to the naza (servo lead) you can just use the signal wire, its only an option to get rid of some wires and weight.The green flashing led on my naza light indicates enough satellites locked in and home position set, ready to fly

hi!thanks for the information mkc2! I did not know that only the signal cable was enough for the connection to the naza.for the problem of LED and gps lock, after an afternoon of research on the web, I opted for a radical solution ... I upgrade the naza and the little has become big ...

It worked, after the reconfiguration I finally had the green flash fast that indicates the gps lock.on the other hand, as much in lite as now, I have the impression that some of my motor turn slightly slower than others ...I took bhleli optos because I thought I did not need to calibrate them but I think it will be necessary ...What do you think ? knowing that I am in sbus, how to proceed?I also have another receiver in traditional connection. do you think I can do the calibration with another receiver bind to my radio and then change with the ia6c?Thank you again for your help !edit: i modify my post ... i am talking About receiver and not transmitter

I use the traditonal setup for receiver, not familiar with the sbus setup.When you get your props on and engaged the motors it may seem different again as they will be spinning fast, see how it goes when you do your first test flight..

hi everyone,thank you all for your messages and your help!I received my props but I have not yet been able to fly the mavic.i tried to calibrate my esc with an old trafitional rx but it made the soul during the calibration of the first esc ... so I ordered a new rx expected to arrive sometime next week.

I will do the calibration with the new rx and I will try to put the current one back in sbus, normally it should work (thank you for the information patrick57).I'll let you know if it helps other people in this case.

Hi,Some news from my mavic, after receiving the rx and calibration of the esc everything was ok to start the first flight!So take off after waiting for gps and compass calibration.

The mavic seems pretty reactive except that it vibrates a lot or rather it oscillates a lot and quite violently ...

I go back on the computer to assign the x2 on roll and pitch of the basics gain.After several tests it vibrated a little less but I do not know why a propeller broke off in full flight ... followed a crash that broke the left back leg ...So I am good to restart my soldering and order new propellers.

So I'm a bit in stress for the rest of the adventure because I did not understand why the propeller is gone in full flight. the prop was tight and in a good way.And why so much vibration I do not understand, if you have any ideas ??

The propellers are 8045 emax nylon bought on ebay, they are fixed (see photo).On the first flight I had set the gain high enough and by lowering it seemed better. but it still vibrated a lot ... maybe it's my propellers that are not adapted.

otherwise I replaced the broken leg and redo all the welds and everything looks good.now waiting for new props , and and your advice on the props
